[Users] real loading

[Daniel-Constantin Mierla]

Hello,

openser does not reply with 481 Call Leg/Transaction Does Not Exist in 
any circumstances. This is created by the gateway which has no active 
call matching the dialog attributes in BYE.

What do you mean by "unstable and almost hanged"? No more CPU? Memory? 
No message forwarding? Any error logs?

Cheers,
Daniel
